Lids, bayonet-joints; lids secured by locks.-In closing- means of the wedging type for milk churns, containers, and vessels in which a conical portion on the lid or cover is forced against a conical seating in the neck or mouth of the churn, &c., the co-operating wedging-members are arranged on an overhanging flange of the lid and the extension of the vessel respectively. The lid is locked by a spring-pressed bolt or tooth which engages a toothed rack on the lid, and is automatically secured in the retracted position by a releasable retaining-device. As shown in. Fig. 2, the lid consists of a thin disk e fixed to a thick conical ring f adapted to fit a tapering surface c on the interior of the neck b of the churn a. The depending flange g of the part f fits over the mouth of the vessel, and is provided with inwardly projecting studs to pass through gaps j, Fig. 1, between inclines d, d<1> on the neck b. The inclines d<1> assist in raising the lid when turning it for removal, and may extend beneath the inclines d or terminate beneath the gaps j. The lock k attached to the neck of the vessel has a spring-pressed bolt l carried by a slide to engage the toothed rack m in the channel part of the lid. When the bolt is lowered by means of a thumb-piece l<1>, a spring-pressed block x, Figs. 8 and 9, engages in the head of a. T-shaped slot w in the slide, and the bolt is held in the retracted position until the block x is disengaged from the slide by pressure applied to the knob o. A card, label, or seal is inserted in grooves k<1> in front of the lock before the lid is applied to the vessel. After the lid has been tightened, access to the thumb-piece l<1> can only be obtained by defacing the cord, &c. A stud t, Fig. 1, on the face of the lock may engage a perforation in the card to prevent the card from being raised or lowered. In a modification, a ring. z, Fig. 12, rotatable on the neck of the vessel is formed or fitted with inclines d<2>, d<3> to be engaged by studs h on the flange g of the lid. Projections g<1> on the lid engage in recesses b<1> on the churn to prevent the lid from turning when the ring z is rotated. In another arrangement, a grooved ring is fitted on the lock case to receive a sealing-disk. As shown in Fig. 16, the lid comprises a stamped ring g<2> of thick metal with an inwardly-projecting flange f<2> to which is fixed a. central flanged and dished portion e<x> of flexible sheet metal. Radial notches are provided in the ring g<2> to receive a bar for turning the lid. The lock has flanges r' to engage grooves in lugs q<1> on the neck of the vessel, and is held in place by a plate s<1>, which is secured by screws s<2> and provided with a ledge s<3> to prevent displacement of the card or label. In another modification, the slide of the lock is acted upon by a coiled spring, and the retaining-block by a V-spring. Specification 102,204 is referred to.

Abstract: 1,007,313. Regulating. RUSTON & HORNSBY Ltd. May 8, 1963 [May 12, 1962], No. 18336/62. Heading F1B. [Also in Division G3] The governor of a dual fuel engine controlling liquid fuel and gas valves 16, 20, through a floating lever 13 and control rods 14, 17, is assisted by a pressure operated piston device 31 acting on a lever 24 controlling changeover from gaseous to liquid fuel. The lever 24, pivoted at 25, has loosely pivoted thereon a lever 42 controlling through a rod 36 the valve 37 of device 31 and stops 29, 31, on the rods 14, 17, co-operate with the lever 24, a light spring 21 urging the lever 15 to the left whilst a strong spring 52 urges lever 24 clockwise. The governor normally moves lever 13 to move rod 17 to operate the engine on gaseous fuel with pilot liquid fuel injection, the lever 24 moving from the no load stop 28 to the high load stop 27. If the gas supply fails, further movement of the governor lever 12 moves lever 13 to operate rod 14 which first moves lever 42 to open the valve 37 and permit the pressure liquid to drain out of cylinder 31, whereby spring 52 moves lever 24 clockwise, permitting the liquid fuel control rod 14 to move to increase the liquid fuel supply. A manual control means 47 can be actuated to override the governor control at starting. Operation of the means 47 actuates lever 42 to connect the device 31 to drain and allow the rod 14 to move to the maximum liquid supply position. Immediately after starting, means 47 is released and valve 37 closes, whereby pressure fluid supplied at 40 forces the piston 32 to the left to return lever 24 to the gaseous fuel operating condition shown.
